Every file shows what it holds before you start. A file with nothing to flatten is left as it is.
Many files
Each file is flattened on its own, and you download them together as a ZIP.
Frequently asked questions
How do I flatten a PDF?
Drop your PDF, keep Forms and Annotations on, then select Flatten and Download.
What does flattening do?
Form fields and annotations become part of the page and keep their appearance. They can no longer be edited as form fields or annotations. Other page content may still be editable.
Will the file look different?
No. Each field and annotation is drawn from its own appearance, so the page looks as it did.
Are my files uploaded?
No. The files stay in your browser and never leave your device.

Is it free?
Yes. No account, no usage limits, and no watermark.
Technical details
Processing
Each field and annotation is drawn into the page from its own appearance in a background worker in your browser. One that has none gets one first.
What stays
Links, file attachments and media stay. An annotation on a hidden layer stays hidden. The form itself is removed once no field is left.

Signatures
A digitally signed file is rewritten, so its signatures no longer verify.
